Rainfall-induced landslides are very common in Malaysia especially during rainy seasons. Some of these landslides have resulted in not only extensive damage to properties but also loss of lives. An investigation has been carried out on one of the major landslides which occurred in Hulu Klang, known to be a landslide-prone area. The study involved: (i) determination of mode and mechanism of failure based on information from site investigation, field data collections and eyewitness accounts, (ii) back analyses and (iii) identification of contributing factors. The failure can be classified as a deep-seated failure caused by existence of high pore-water pressure within the slope. The landslide may be attributed to a combination of factors such as: existence of loose soil from earth dumping on the slope which took place during the development of the area, prolonged rainfall during the months of October and November, widening of existing cracks and opening of new tension cracks due to prolonged creep and lastly damage of water pipe due to soil creep.KEYWORDS: Landslide; pore-pressure; back-analysis; tension cracks; soil creep.
Keywords: Landslide; pore-pressure; back-analysis; tension cracks; soil creep.
